| In this thesis, based on Ji’nan city highway south line tunnel project, experimental study on diagnosis and treatment of tunnel disease is presented, through the tunnel of Shandong province, alongwith geological conditions, hydrological characteristics other limestone area, design construction, operation and disease conditions, The constrcction and maintenance of tunnels in limestone ateas have been re-evalcated. The following aspects have been studied in this thesis.①Through the investigation of Ji’nan tunnel disease situation, the influence of tunnel disease on the safety and regular operation have been analyzed.②Base on the causes of common diseases in limestone area, the disease diagnosis technology in limestone area tunnel has been summarized.③Combined with the tunnel disease diagnosis technology in limestone area, the minimally invasive treatment technology in the tunnel construction,water leakage has been invasive treatment technology.④The new technologies in tunnel disease treatment has been studied, The minimally invasive technology in lining crack seepage water leakage has been developed.⑤To summed up, the tunnel disease prevention method in limestone area, The minimally inbasive technology in tunnel has been introduced. The new ideas including tunnel detection,maintenance and so on have been introduced. |
